Dry ice hazards_presenting which hazards?

• A. Explosion
• B. Suffocation
• C. Severe frostbite
• D. All of the above

Answer: (D)

Dry ice is solid carbon dioxide that sublimates into gas at room temperature. As it releases CO2, it can accumulate in poorly ventilated spaces, displacing oxygen and creating a suffocation hazard, especially in enclosed rooms or cargo holds. Its surface is extremely cold (-78.5°C), so touching it can cause severe frostbite; always handle with insulated gloves and use tongs. If dry ice is placed in a sealed container, the gas build-up increases pressure, which can cause the container to rupture—an explosion-like risk. Because of these three distinct hazards, dry ice presents explosion risk, suffocation risk, and frostbite risk. All of the above applies.
